Re: JULIA
Julia doesn't know if her other friends are coming so when she sees Loki, she accepts the invitation. But as soon as she's seated, she's glad that she did. Julia is... her feelings towards gods are always complicated, but she's eager to hear more about Frigga. She'll listen, absorb anything Frigga has to say, and is respectful.
Loki is being weird but, Julia doesn't question it. Not then and not in front of Frigga. She tries not to look like she's keeping a metaphorical eye on him, trying to pick up on context clues in this interaction/dynamic with his mother. Is he trying to impress his mom? Is he attempting to use Julia to impress his mom? Because Julia isn't sure there's anything good that would be impressive about her...
